What are Hemorrhoids?

Hemorrhoids (also called piles) are swollen blood vessels in the rectal or anal area, often caused by straining, constipation, or prolonged sitting. They can be internal or external, and vary in size and severity.

Hemorrhoids Grading and Size Chart (Internal Piles)

Grade Size Prolapse Status Symptoms Common Treatment
Grade I Small (≤0.5 cm) No prolapse Bleeding, discomfort Diet changes, creams
Grade II Moderate (0.5–1 cm) Prolapse with straining, retracts on its own Bleeding, itching Rubber band ligation, sclerotherapy
Grade III Large (1–2 cm) Prolapse requires manual reduction Pain, bleeding, swelling Stapler surgery, banding
Grade IV Very Large (>2 cm) Permanent prolapse, cannot be pushed back Severe pain, leakage, thrombosis Hemorrhoidectomy, laser surgery

Experiencing Any Of These Piles Symptoms?

Key Differences in Hemorrhoid Grades

  • Grade I: Only visible through endoscopy, usually painless.

  • Grade II: May protrude while passing stool but go back on their own.

  • Grade III: Needs manual push-back after prolapse.

  • Grade IV: Always outside, risk of clot formation (thrombosis).

Types of Hemorrhoids

  • Internal Hemorrhoids

    1. Located inside the rectum

    2. Painless bleeding

    3. Classified by grades (I to IV)

  • External Hemorrhoids

    1. Located under the skin around the anus

    2. Painful, may form clots (thrombosed)

    3. Not graded by size, but by symptoms

FAQs

What is the most severe grade of hemorrhoids?

Grade IV is the most severe and usually requires surgical removal due to permanent prolapse.

Can Grade I hemorrhoids go away on their own?

Yes. With lifestyle changes and topical medications, Grade I hemorrhoids often resolve without advanced treatment.

Is size the only indicator of hemorrhoid grade?

No. Grading is based on prolapse behavior, not just physical size.

Can hemorrhoid size increase with time?

Yes. If untreated, hemorrhoids may worsen from Grade I to IV, increasing in size and symptoms.

Are external hemorrhoids graded the same way?

No. External hemorrhoids are not graded but assessed based on pain, size, and clot formation.

    I had visited for piles issue. Doctor was very polite and explained everything properly. He gave some medicines and diet changes. Within 5-6 days I felt much better. Only giving 4 stars for treatment bcoz I still had slight discomfort while sitting. But doctor is 5/5, really experienced and helpful.
